VALVE-LIFTING TOOL.

Application filed May 23,

To all whom it may concern Be it known that I, THOMAS MANNA, a citizenof the United States, and residing at Jersey City, in the county ofHudson and State of New Jersey, have invented certain new and usefulImprovements in Valve-Lifting Tools, of which the following is aspecification, such as will enable those skilled in the art to which itappertains to make and use the same.

This invention relates to valve lifting tools or tools of this classdesigned for the purpose of removing poppet valves from gas engines andthe like, and the object of the invention is to provide a tool of theclass specified composed of movably connected handle members with meanscooperating with said handle members for autoing jaw membersof differentsizes in connection with said handle members whereby a tool may be usedin removing poppet valves of various sizes andof different forms andconstruction; and with these and other objects in view the inventionconsists in a tool of the class and for the purpose specified which issimple in construction, efficient in use and which is constructed ashereinafter described and claimed.

The invention is fully disclosed in the following specification, ofwhich the accompanying drawing forms a part, in which the separate partsof my improvement are designated by suitable reference characters ineach of the views, and in which Fig. 1 is a side view of my improvedtool with part of the construction broken away and in sect-ion, andindicating the method of its use;

Fig. 2 a viewsimilar to Fig. 1 but showing the tool only and with theparts in a different position; and,

Fig. 3 a partial section on the line 33 of Fig. 1 and on an enlargedscale.

In Fig. 1 of the drawing, I have shown for the purpose of illustratingthe use of my improved tool a part of an explosive engine 5 with apoppet valve 6 mounted therein through the shank of which is passed apin 7 for retaining a spring seat 8 in a predetermined position on theshank, and at 9 is shown a spiral spring adapted to operate inconnection with the seat 8.

My improved tool 10 comprises two mem- 1922. Serial No. 562,361.

bers 11 and 12 provided at one end with socket members 13 and at theother end i in Fig. 3 of the drawing, and the ends of which are forkedto receive the members 11 and 12, and rivets 16 are passed through theforked ends of the link 15 and through the members 11 and 12.

The socket members 13 are provided with angular recesses 17 which openoutwardly through the ends of said socket members and are adapted toreceive angular shanks 18 of detachable jaw -members 19, the outer orfree ends of which are forked as shown at 20. It will be understood thatthe. jaw members 19, the forked portions of which maybe of differentsizes, may

be mounted in connection with the socket members 13, or the members 11and 12,

the angular shanks 18 of said jaw members being of the same size so asto fit the recesses 17 of said socket members.

Mounted upon the inner'face of one of the handle members 14 is aU-shapedblock 21. within which is pivotally mounted a lever 22 which issubstantially L-shaped in form, and one part 23 thereof extends upwardlyand is adapted to pass'through an aperture 24 in the other handle member14, and the part 23 is provided on one side edge thereof with aplurality of spaced teeth or projections 25 adapted to cooperate with-abeveled edge 26 of the aperture 24 to retain the handle members 14 inpredetermined positions of adjustment with respect to each other.

The other part 27 of the lever 22 extends forwardly in the direction ofthe movable connection of the members 11 and 12, and one end of a spiral28 is connected with the part 27, the other end of said spring beingconnected with a suitable part 29 secured to the free end of the firstnamed handle member 14, as clearly shown in Fig. 2 of the drawing.

The pivotal connection of the lever 22 with the U-shaped block 21 ispreferably made by a bolt 30 so that said lever may be detached,whenever desired, to compactly fold the complete tool together forshipment or other purposes.

The use of my improved tool will be readtion when taken in connectionwith the accompanying drawing and the following statement. It will beunderstood that when it is desired to use the tool, the handle mem bers1 1 are separated to bring the aw members 19 together as shown in Fig. 2of the drawing, and one of said jaw members preferably the lower jawmember, is placed upon a fixed support 31 ofian engine cylinder and theother jaw member 19 is placed between the spring seat 8, after which thehandle members 14 are moved toward each other, or the upper handlemember is moved toward the lower handle member, in which operation theaw members 19 are separated and the spring seat 8 is raised out of engagement with the pin member to permit of the removal of such pin fromthe shank of the poppet valve 6. It'will be understood that when the jawmembers 19 are in the posit-ion shown in Fig. 1 of the drawing that thepart 23 of the lever 22 will operate to retain the handle members 14 inposition, and this will enable the operator to use one or both hands inthe removal of the pin 7 after which the lever 22, or the part 23thereof, may be moved backwardly out of engagement with the upperhandle1 1 to allow the jaws 19 to again come together.

'It will be apparent that the spring 28 operates to hold the part 23 ofthe lever 22 normally in engagement with the beveled edge 26 in the wallof the aperture'24c in the upper handle member 14 to automatically locksaid handle member in predetermined positions of adjustment. It willalso'be understood that while I have shown certain details ofconstruction for carrying my invention into effect, that I am notnecessarily limited to these details, and various changes therein andmodifications thereof may be made, within the scope of the appendedclaims, without departing from the spirit of my invention or sacrificingits advantages.

Having fully described my invention, what I claim as new and desire tosecure by Letters Patent, is

1. A valve lifting tool of the class described comprising twosubstantially simi lar members provided at one end with angularsocket-s, a link pivoted to said members adjacent to the sockets thereoffor movably connecting the same, one of said members being providedadjacent to the other end thereof with a U-shaped part, a substantiallyL-shaped lever pivotally mounted in connection with said part, onemember of the lever being adapted to extend through an aperture in theother of said members and provided with teeth or projections adapted toretain said last named member in predetermined position with referenceto the first named member, and fork-shaped jaw members detachablymounted in connection with the sockets of said members.

2. A valve lifting tool of the class described comprising two similarhandle members provided at one end with sockets, forkshaped jaw membersadapted to be detachably mounted in connection with the sock- .ets ofsaid handle members, a link pivoted to both of said handle membersadjacent to the sockets thereof for movably connecting said members andfor spacing the same one from the other, and means mounted in connectionwith the other end portion of one of the handle membersand cooperatingwith the corresponding end portion of the other of said handle membersfor interlocking the same and retaining said handle members in spacedrelation.

3. A valve lifting tool of the class described comprising two similarhandle members provided at one end with angular sockets, U-shaped awmembers adapted to be detachablymounted in connection with the angularsockets of said handle members, a

link provided with fork-shaped extensions spaced between the handlemembers adjacent to thesockets thereofand into the forks of which thehandle members are pivoted for connecting said handle members one withthe other, and means carried by and movably mounted on one of saidhandle members and cooperating with the other for interlocking the sameand retaining said handle members in spaced relation.

In testimony that I claim the foregoing as my invention I have signed myname this 20th day of May, 1922.

THOMAS MANNA.
